cam and wiper kit. A 15-volt photoflash battery, Eveready no. 504 or equivalent (not supplied), is required to operate the systern. The module, speaker, battery, and the on/off switch are to be mounted in the locomotive tender. The speaker supplied with the system can be cut down so it can be fitted into most large HO tenders. Smaller, and larger, speakers are also available from the supplier. The dimenSions of the other two major items to be tender-mounted are: Electronic module: %" x %" x 1%". Battery: %" x %" x 1%". Despite the battery's small size, it can be expected to last a long time. We tested our sample Tru-Sound system for 20 hours and the battery was still going strong when the test was terminated. The most difficult part of the installa- tion is fitting a cam to the locomotive axle and installing a wiper to ride on the cam. One wire must be run from the sound module in the tender to the cam wiper. The cam and wiper synchronize the exhaust blasts to the driver rotation. The cam is to be fashioned from a steel nut which is supplied. The cam installation procedure is explained in the instructions supplied with the kit. The sound produced by the Tru-Sound system is very realistic. [ Since this review was prepared, Tom Hunt has produced a second model of this unit, selling for $19.95. The basic module is .375" shorter than the one described, but there is a separate outside tubular capacitor to be connected to it. We are told this will fit most equipment that the reviewed unit fits, and it may fit some other engines or tenders that the reviewed unit will not-all depending on making use of the shorter length and finding a place to tuck the capacitor. The electric circuits and performance are identical, we are told. The difference is that maker's costs are lower with the substitution of a physically larger capacitor outside the module.] HO country schoolhouse Campbell Scale Models P. 0. Box 121, Tustin, Calif. 92680. Price: $7.95. We've often said that the best model structures are exact or condensed versions of actual prototype structures. Campbell's schoolhouse bears this out. The model is reproduced from a school built in Iowa in 1879. It is typical of the many rural one-room schoolhouses built throughout the United States. The well-proportioned model scales 18'-9" wide and 24'-0" long with a 3'-9" x 7'-0" lean-to at the rear. The two-door outhouse is 3'-9" x 8'-0". Also included in the set are a swing and a teeter-totter. The wood material in the kit is milled close-grained pine. All building walls come precut to size. Window and door openings are also precut. Wood trim materials are to be cut to fit by the modeler. The roof panels are cardstock printed with lines which help one position the rows of brown paper shingle material supplied. The school wall vent windows, door, bell, and bell cupola braces are cast plastic.
